There appears to be a lot of choice and fiddling required to become proficient in 3d-printing. Without having a personal killer-use for one I've so far managed to get several things printed by downloading the designs from thingiverse and paying other people to make them for me, on a per-print basis. Having 3d-printed things is pretty cool, makes my electronics projects look a lot more professional, but I still suspect if I bought a printer of my own I'd be frustrated and annoyed.
